The new Cepheids have periods in the range from 0.34 to 9.1d and cover the magnitude interval 12.9≤<Ks>≤17.6mag. Our method was developed using variable stars previously identified by the optical microlensing survey OGLE. We focus on searching new Cepheids in external regions of the SMC for which complete VMC Ks-band observations are available and no comprehensive identification of different types of variable stars from other surveys exists yet. Description: We have developed a technique to identify variable stars using only the multi-epoch near-infrared photometry obtained by the VMC survey and have specifically tailored it to the identification of Cepheids. The technique exploits colour-magnitude and colour-colour diagrams, and PL relations defined by known SMC Cepheids, along with template parameter selections and visual inspection of the light curve to identify bona fide Cepheids. The technique was applied to external regions of the SMC for which complete VMC Ks-band observations are available and no comprehensive identification of variable stars from other surveys exists yet. We have identified and present Ks-band light curves for 299 SMC Cepheids. File Summary:
